Portable App Development

I'm not sure this is the right place to post this, but i was playing around with the splash screens for the apps on this site, and if you use the "Flatten Image" option in GIMP, then save the splash, the size for a majority of the splash screens is nearly cut in half. Not only does this save space because the splash is smaller, but if you recompile the launcher after doing this, the launcher takes up less space at all.

can i have a portable apps suite download in zip format? please..

I found out a way to make portable apps. I was very rushed when making this, so please post any problems here.

EDIT:Updated to 2.1 Download 2.1 here

What can be done about an application that works with registry, and working under a limited account? now registry can't be edited in anyway.

I found two portable apps that are very useful- 7-zip and AbiWord.Have always used Firefox (now 2.0.1) which the whole program directory was just copied to my USB Flash Drive. With a little tinkering it worked pretty well and complete with the add-ons, except I never realized I was leaving tracks on other machines. Of course, I have now switched to Fx Portable. I have found out that most of my favorite web apps (download manager and WinHTTrack are inherently portable.

Is the source to the StartPortableApps available anywhere, Ive looked on source forge and im either being really dense or its not there. Im also guessing its another fine NSIS script?

Thanks

Is there a tutorial for creating portable applications?
I downloaded NSIS but it looked so hard
anybody can help?

I saw by many portable apps that
they run some code/exe

then the programs starts.

after you close the program again a program or batch file runs that removes certain files.

how would I do that?

I'm trying to edit the Portable Firefox launcher, but I don't want to figure how to make an NSIS configuration file from scratch, so I was wondering if there was somewhere I could get one, if not necessarily for the Portable Firefox launcher, at least for one of the Portable Apps.

Is there ant plans of a a type of password prompt (when you insert the usb drive it prompts you for a password before you can access the menu) addition to the Portable Apps menu. If so I'd like to know when the addition will come out. Thank you
