Hello Guillaume,
Yes.
If you format it as a table it will line up the images. For the image size it works best to upload your images to the preferred display size (no smaller then 50x50px).
Disadvantages:[br]
'''1.''' A border appears around images.[br]
'''2''' does not adjust to screen sizes. (for size=small only 2 images would be safe side by side)[br]
[br]
'''Example Code''' - ''2x2 grid'' [br]
[code]
{table
| [image|125525|size=small]
| [image|125525|size=small]
|--
| [image|125525|size=small]
| [image|125525|size=small]
}
[/code]
