i have found this app really useful for downloading certain file types from websites as it doesnt take a load of right clicking to use it which is normally a slow process. it gives you a thumbnail view of images and view of the files then you just select the ones you want to download and it does the rest. it queues them up to be downloaded to a selected directory and you can limit the number of downloads allowed at one time as well as the searches and such. any possible way of making it portable. there is a free version on the website and i am yet to find anything like it that is portable.
