Error uploading image, wrong file type

I have a slightly different issue. I feel certain it is addressed somewhere, but I cannot find it, so if it has been addressed and someone knows where, could you please point me to it.

I am a user on a forum that uses v.9.5. Many of the members there cannot upload images and avatars. Most of us can, out of 300 or so members, there are probable 30 that are really active posters, of the thirty, probably 5 cannot post images.

Since most of us can, I figure the problem is not with the forum software, but with some settings on their own computers. Does anyone have a solution to this that I can pass on to them? The administration  of those forums are inactive, and I don't think they know much about the software or care to. Anyway, I would appreciate it if someone can point me in the right direction and maybe help these people out.

Thanks a lot.

Hi omegaman
I'am working on upgrading from version 9.50 to 9.70 due to this error.
The problem is in module: functions_upload.asp, which has changed in version 9.70.

A hack to solve the problem until you have upgratede is:
1. Find the section     '***  Security check for MIME change   **** (line 501)
2. Find the code lines (line 579)
        'If the file extension is not OK then delete file
            If blnExtensionOK = False Then file.Delete
3. Before this you insert the following lines
            If not blnExtensionOK then
                If lcase(right(strNewFileName,3)) = "jpg" or lcase(right(strNewFileName,4)) = "jpeg" or lcase(right(strNewFileName,3)) = "gif" or lcase(right(strNewFileName,3)) = "png" then
                    blnExtensionOK = vbtrue
                End If
            End If

Please remark: This hack overrules that security check, that the uploaded image file may not be an image.

good luck
