I have an upload form for images that once uploaded are then displayed automatically and randomly on a website. I would like to apply a colour tint to the images before they are saved, at the very least one green but preferably various colour tints which are saved in relevant folders /green/ /red/ /blue/ etc. so I can make skins for the site.
My hosting package doesn’t allow me to install imagemagick so I’m looking for a way to achieve these results in html css and php preferably, as that’s where my limited knowledge lies, but if that’s not possible I will consider other options.
is gdlib enabled?
or you use aviary or one of their apis http://developers.aviary.com/filter-list

Update: as Aviary is no more offering this service as before but here are some more good solutions:
take a look at Pixastic (coloradjust)

or PaintbrushJS (colour tint)
