Haha, what I mean is that there is no JPG in the attachment format of this forum.
PNG format has the smallest size without losing image quality. You can compare converting the same BMP image file into PNG, JPG and GIF formats. The true-color PNG format is even smaller than the 256-color GIF format. Of course, there is no point in converting if it is already in JPG format. So the forum has disabled the upload of JPG format files.
In addition to providing software to members, these illustrative image files are best linked externally.
Please try to use external links first, then consider the
China DOS Union File Upload System, and only use the attachment upload form as a last resort. And when uploading images, please try to use lower color depths if they can illustrate the problem.
The forum has been closed a few times before due to exceeding space limits. Thank you for your cooperation.
