Submitting screenshots

Hello.

I'm unable to submit screenshots.

For example: whenever I try to submit a screenshot (in PNG format) it shows this error message: [imgur.com]

If I try to submit a screenshot in other formats (BMP, JPG) it show an error message like: "File 'image.jpg' has a false extension".

Am I doing something wrong? I select/write in all the required fields. I tried taking screenshots from different emulators or creating with image editors. The errors are always the same.

Thank you for your attention.
Keep up the great work!

Now it worked!

Thank you for your attention!

Best regards!

... about the resolution of screenshots, I have a request...
What the use to upload screenshots with the same resolution of the thumbnails?
For example, if a thumbnail is 256x192 for a quick preview, what's the reason to have the same screenshot for the plain view?
I always make screeshots with blueMSX at 544x480 and Gen-MSX engine makes automatically the thumbnail.
This is an example, so you can see the differences:

People have different ideas about screenshots. Some sites like mobygames insist on original resolution, which is pretty small on a modern display, especially new UHD (4k) displays. So small in fact that they are often unreadable unless you use some magnifying tools.

GenMSX does not have a real policy, and it is really up to the submitter. I prefer to get screenshots for MSX1 games on an MSX1 due to the colour differences with the MSX2. I also don't like to do screenshots with shaders added. But I'm personally fine with a 2x or 4x scaling (avoid fractional scaling as it causes distortion).
