ImageAPI GD Memory Limit

Salut

dans le status report je obtiens ceci

--------------------------------------------
ImageAPI GD Memory Limit 32M

It is highly recommended that you set you PHP memory_limit to 96M to use ImageAPI GD. A 1600x1200 images consumes ~45M of memory when decompressed and there are instances where ImageAPI GD is operating on two decompressed images at once.

Comment je peut augmenter la PHP mémoire à 96Mo avec .htaccess

(j'ai un hébergement mutualisé)

merci
