Okay I have placed my first photos from my new Canon Rebel SL1 in iPhoto '11 ( 9.43) on my again MacPro 1,1 running 10.7.5. No problem. They show as 526KB and 2.9MB jpegs in iPhoto. I export set to full size everything to desktop. Files now 1.2MB and 6.4 MB. I email them to a friend and they wind up as GIF size files of 22kb and 13kb. I then email them to myself, both via Mail and AOL --- numerous times, attaching one or both, using Windoze Friendly or not, with new exports from iPhoto. They all wind up as miserable 22KB (1.2MB file on desktop) or 13KB ( 6.4MB file on desktop) attachments. I've never noticed this before and can find nothing in all my settings to suggest a probelm. Just had a brand new Firefox update? I also installed and update lots of Canon Software with the brand new camera. Canon SU seems to work just fine on computer. Is it coincidence that the first time this happened was after the update to Firefox 28.0 Sorry to dump this here. But my head is spinning trying to digest the Rebel SL1 -- Canon's "entry leve"l DSLR, that I picked to share with my 14 year old grand daughter who is showing a great eye.
