When using it, if I directly open the image with FlyPhotos on the image, it freezes after opening. Attached is the log

 Hello developer, my English is relatively poor. I used a translation software, so my expression may not be very good. Please forgive me. The following is my usage log.

1. Does the app start working again if you wait for some time?

2. From the log, it looks like Fly is facing difficulty to open (decode) AVIF images.
   Can you please share some sample AVIF images for testing?

3. Does the problem still happen if the folder has only JPEG images?

[riyasy]

Some more questions -

4. Did you install Fly from the free MSI installer or from the Microsoft Store?

If you are using the free version, please check this:

5. Some antivirus programs may block Fly because the free version is not code-signed. Can you check if your antivirus is blocking it?
6. Did you do a clean install? (Did you uninstall the old version before installing the latest version?)

[MaMihLaPiNaTaPaI0]

I apologize for the delay, I will answer one question at a time. If the translation software offends you in terms of expression, please forgive me

1. No, it crashes after opening the image without further action. The image can be opened and displayed normally, but the program closes itself automatically after one or two seconds. And any clicks during this process are ineffective.
2. AVIF seems to be downloaded from a webpage, but it was downloaded directly as a PNG using a browser conversion plugin. Please give me some time to find out which image it is. I moved the image to another location, and since I have many images, I forgot which one it was. I will send it later.
3. Currently, only this folder exhibits this behavior because I only have two or three image folders. I have been using them for just a few days. Thank you for your hard work
4. It's being used for free because I wanted to try it out first before paying. There are too many programs out there now, and it's hard to find one that suits me.
5. No antivirus software is being used. I don't download programs randomly.
6. It was a fresh installation. When it 出错 ed, I uninstalled and reinstalled it.

But I have moved this downloaded image from the download folder to another folder, "H:\Miscellaneous Downloads Collection" is my default download folder, maybe it's another file causing the issue?](url)
This image file, even after downloading without converting the format and placing it in another folder, can be opened and used normally,
Currently, the only time it behaves this way is when opening it in the default download folder (I've used the program to open it in about three or four folders).
I don't know how to provide information that would help you improve...

a6351156e1e7dff83dd8feee4696f820ea956192.png@1256w_942h_!web-article-pic.zip

I think it might not be the problem with this image...
In my default download directory, there are many various files, and I don't know which file is causing the program to malfunction

[riyasy]

If the same image can be opened when copied to another folder, then the issue may be with other files present in the "H:\Miscellaneous Downloads Collection"

When we open one file in a folder using Fly, it starts to pre-load nearby image files in that folder. I suspect such a file in the "H:\Miscellaneous Downloads Collection" is causing the issue. Ideally, even if a file is problematic, the app should not freeze or crash.

Also I shall check the image in two days as I only have a mac machine with me at the moment.

[MaMihLaPiNaTaPaI0]

I think it's an issue with other files. Just now, I checked all the images by file extension, and the .webp images can be opened when moved to another folder. The images I provided can also be opened in another folder.
Is it a language issue? My system language is Simplified Chinese, but other interface programs use Traditional Chinese.

If you need help, I'm happy to provide information from the default download folder, but I don't know what to do to assist you.

[MaMihLaPiNaTaPaI0]

This is all the extensions in my default download folder.

[riyasy]

I don't suspect the language at the moment.

Please copy all image files from this folder:
H:\杂七杂八下载集合\

File types to copy:
AVIF, GIF, JPEG, JPG, PNG, WEBP. (as seen in your screenshot)

Put them into a new empty folder.

Then open one image in Fly from this new folder.

Check these:

Do the thumbnails of other files load?
Can you move to next/previous images?

[MaMihLaPiNaTaPaI0]

I think I've found the problem. After moving all image files one by one and then opening them, I discovered one image file
4b86d199283b56539e1da6308772f27930396942.jpg@!web-comment-note.avif.jpg
I changed the suffix to JPG. When I deleted the JPG, 4b86d199283b56539e1da6308772f27930396942.jpg@!web-comment-note.avif could be opened. And it didn't crash.

[riyasy]

That is good news. Thank you for finding the file.

Even if a file has a wrong name or format, FlyPhotos should not crash or freeze. I will check and fix this.

If you don’t mind, I have two small questions:

How did you find FlyPhotos?

What 3 small features would improve Fly the most for you?

Thank you for your help.

[MaMihLaPiNaTaPaI0]

You're too polite, I'm very willing to answer.
I was looking for a faster and more lightweight image viewing tool, and found this program while searching for image browsing tools on search engines. I didn't use an antivirus software, so I directly downloaded it from the project address.
I haven't been using it for long, and haven't encountered any other major issues so far,
For me, I'd rather the close button in the upper right corner not appear when I press F11, or be able to automatically hide, because ESC can exit, and sometimes when I take a full-screen screenshot, that close button is quite intrusive.
XD

[MaMihLaPiNaTaPaI0]

Oh, by the way, there's another issue. I'm using an LG G502X. The left and right buttons on my mouse wheel don't switch the images.

[riyasy]

In the LG G502x, Are the right and left keys mapped to any event ?

[MaMihLaPiNaTaPaI0]

They are the defaults
