Those excel sheets all went Jamd fubar, and even PhotoXpress does not offer any free images to new users anymore.
Fotolia´s new offer to some bloggers (a few selected ones of course from the design and media world) instead now gives to these bloggers the possibility to download up to 5 images per day from the Standard Subscription (not the Premium Subscription) in L-Size - limited to a full month nota bene.
The images are coming from Fotolia, not from PhotoXpress.
