Thread:Project:Support desk/1.24 mediawiki, can't display 24bit .png file./reply (2)

Dear Ciencia AI Poder, This happens for some images such as screenshots images which are caught thru keyboard (shift+PrtScn) and saved as 24 bit .png or .jpg file by mspaint tool. But if these screenshots images were same as 16 bit .png, they can be displayed in mediawiki. Some images like the windows 7 system original images(.jpg) also can't display in mediawiki(no size limit issue in mediawiki, hava changed size limit). But if I edit the windows 7 system original images thru mspaint tools and save the edited image as .jpg file, these edited images(.jpg) file can be displayed in mediawiki.

Due to some restriction to upload attachment by private network, I am trying to attach it in the website. Attached debug trace of a failure displayed 24 bit .png image below:
