image problem

[nvinvi]

I have installed xampp
and have some trouble with big jpg image (more than x K?, I don't know exactly the size limit)

Sometime I don't get the image sometime I get a scambled image (the beginning is correct and the end is damaged)

There must be something in the apache setting regarding the size of images !!

I have no trouble when using an easyphp installation.

Somebody can help me to switch to xampp?
thanks
