Can you briefly explain this? I don't understand what prevents this from replacing all instances of '.'.

devtakh, although it took me a minute to figure out how to use this witha longer path, it works very well. Thank you!

Code:
echo './tmp/1.jpg' | sed 's#^[.]#/home#'

'^' signifies 'the beginning of a line.

But removing the ^ still only replaces the first instance?

Lastly, I'm trying to remove the 1.jpg and just leave /home/tmp/, but I am not able to acheive this doing the following:
Code:
echo '/home/1.jpg' | sed 's#/*[.]jpg##'

I am left with the trailing '1'.

if you have Python, here's an alternative
Code:
import fileinput
for line in fileinput.FileInput("file",inplace=1):
    line=line.strip()
    if line.startswith("./"):
        print line.replace("./","/home/")

output:
Code:
# ./test.py
/home/tmp/1.jpg
/home/tmp/2.jpg
