Linking from other websites?

I noticed in some tutorials the tokens are found from other web pages and are tagged. Please forgive my newbiness here. However, what I am wondering does this download into your own personal space or remain just hyperlinked from the other page? Reason I ask I signed up for mentor. I also need to stipulate I haven't ran a campaign yet in Roll20. I am in the process of creating one. Yet, I know with some of the things I would like to do I may exceed the limit. Being an intermediate web designer I know space is a lot, but just in case ;) I do have my own personal web page, and would like to upload things to there and cross it over to Roll20 without taking up the space. Is this possible? For example, I would like to make a token for all the encounters possible in my campaign world. Granted the size for the pictures is nominal. Yet, consider the variables. Like say an Android. Android carrying a spear and shield, Android carrying a 45 and shield, Android carrying a laser pistol and shield, so on and so forth. Not to mention the variables in this, i.e. a shield that is a stop sign, a shield that is a car door, a whicker shield and so forth. Granted it might be "over-kill" yet variety makes things fun too...not so cookie cutter. Yet if you say take all the variables multiply it by say 100-400 monsters, you can see the storage space becoming an issue. Hope this makes sense.

Tokens found on other sites via the search function does not take up space in your Storage Quota. With that said, as a Mentor you have 2 GB of storage quota space and you probably won't run out of that anytime soon. You can check your available space here: <a href="https://app.roll20.net/account" rel="nofollow">https://app.roll20.net/account</a>

Thank you for the response. I highly doubt I will run out. However, being a novice web designer (well intermediate maybe LOL) I know that some things can take some mucho space. I think the closest I ever came to a 2GB space was like about 500MB. However, with the fact that I could be looking at like 400+ encounters with about 70 or so variations it could be a lot. I am possibly looking at sound effects and vid to enhance the whole experience. The campaign I plan is very much in its infancy but it has been something I have been running for about 20+ years and friends from all over the country have requested I pick up the ol "dice" again and run it. So I wanna give em a good run :) Thank you again!
