I apologize for responding in english, but my French is barely good enough to read, let alone write...
If I understand correctly, you need to add 2500 images to a table, and you're running out of memory. My suggestion is, if many of those images are the same, wherever you have a contiguous set of cells that use the same image, you should use FillTableCellRange to set the image. This way, the table knows that those are all the same image, and it will not create individual bitmaps to store them in. Otherwise, if you set the images one at a time, it will not know when they're identical, and will store individual bitmaps for each cell.
