you can try stuff like DEVIANTART, i don't think they have upload limits, but good luck to you, if you are trigger happy. i remember a 2-3 mb file took me nearly 5 minutes each time in the past on singtel broadband 10mb plan.
for something fast and reliable, flickr isn't expensive at all.
I rarely hear people back up their files online. Get another external hard disk then, if you are that kiasu. Or, if you really want to store your stuffs online, I suggest you should zip them (compressed them) and upload as a whole to file hosting website. Otherwise you would take forever to upload and retrieve.
your images cant be very important to you if you are using a photo hosting site (free) to back up the images...... so try this..... dont shoot in RAW.... shoot JPEG at a lower resolution so that you can store more images and more quickly online
I find your logic strange...... you pay so much for a 7D but you are stingy on storage...... a 1T or 500G external harddisk is not alot of money these days
ed9119 - i already have a 2.5tb external.... full.... i need a place with huge limit so i can put my pics ya? and as i've said, i'm bleeding from my purchase ya? and i don't want to be using a paid account as nowadays, EVERYTHING can be gotten for free so why waste the money ya?
