ActiveX image and size of file

Hey there !

I have a question. I put an ActiveX image on a worksheet, but the file has became so slow since that. The size increased from less than 3MB to more than 45MB !

I was wondering if it was normal or not, and how could I avoid to use ActiveX image ?

Actually, I need to put different pictures in my worksheets, each of these pictures opening only 1 userform but loading differents pictures in this userform.
I used a class modul in order to add each image of the worksheet to a collection.

First, I tried a macro increasing the size of the picture directely in the worksheet, but after a few clicks, the quality of the picture was really bad !

Thanks



By the way, sorry if my english is not that good, I'm French, but did not want to use the "foreign" part of this forum, thinking I would have better answer here.
