I'd like to upload around 150.000 small jpegs (around 100 Kbytes apiece) to a number of galleries, each containing 2-400 pictures. Would that result in any problems of a technical nature? I.e. will ZF handle these amounts a data - 15 Gbyte, say - without difficulty?  

Thanks for your input!

you should not have any problem uploading those images...  I'd say go for it and happy uploading!  :)

Thanks for your swift reply! I'll be uploading as happily as I can.
