Change in File Format

[DiamondCloudMom]

I had to send a presentation via the web for a class.

We were required to use JPEG or GIF only in the presentation.

The file I sent was within specs, only JPEG and GIF files.

When the instructor received the file, all GIFs had become PNGs.

Any idea what happened?

I guess I don't really understand how anyone could tell that GIFs had become
PNGs in your presentation. Did the instructor mention how he/she determined
that?

I use PowerPoint2003.

I developed the PowerPoint presentation for class. The properties of the
graphics files in the presentation on my harddrive are GIF format. However,
the properties format of the graphics on the file the professor sent back
were PNG.

This file was sent via an internet explorer website, uploaded to an account
for the professor, and then the professor downloads or views the file. I do
not know what version of PowerPoint the professor uses.

The college student services told the professor there was no way for the
files to change format, however, I have seen the proof as compared between
the file I sent to the professor and the graded file returned by the
professor. (No, I do not believe the professor changed the format of the
graphics).

Any ideas?
