Terminal timing out with wget
Below is an example syntax for how you can manage this:

wget --tries 10 --waitretry=30 -—wait=20 --random-wait -—referer="" -i septweetsimages.csv


In the above syntax, if wget encounters a failure, it'll retry 10 times with a waiting period between each attempt of 30 seconds. It also waits up to 20 seconds before downloading each new image.

Using the man wget command in terminal will provide a description of many other options you can use to manage bandwidth, capture a log file, etc.
