Hi,

is there any way to customize a webpage while it's loading?
I tried adding a javascript that would e.g. make thumbnail pictures bigger

But it usually was like, webpage loads, everything is displayed and then the thumbnail pictures got replaced.

I wonder is there any way to customize it earlier in the loading process? So before swap the picture url's before it even starts to load the old pictures?

Welcome to ChromePlugins

I think sites need to be fully loaded before java kicks in

If your talking about making an extension then next time could you please post your question in the plugins development section so as we know what context to take the question in.
Assuming this is about extensions....
Try changeing the run_at bit of your manifest to document_end. Your page may very well still be loading pictures when your script runs but it will be alot sooner than the default for run_at which is document_idle. Your only other option is document_start but the DOM isnt even created then and you cant get the source for the page mess with it and give it back to chrome to render the DOM (pity, that would be so f### cool). If your real dessperate you could maybe do a timer thingie at document start to keep running a function every few milliseconds to keep checking to see if the dom is created yet and then use another function to keep checking the dom to see if any of your elements have been created and change them. Or I think theres some Events to see if an element has been added and you could hook into them once the dom has been created (their called Mutation Events, but how much chrome supports them and whether they would be what you need I cant say)....but that could get messy...I dont know, never done this, just thinking out loud
More information.......

Well yeah I was kinda looking for a Way to mess with the source and stuff before the resources (images, flash etc) are being loaded and before it starts building the website.

Maybe even as far as having an algorithm that cuts out information of the original website and provides this information for a customized template that is being used to build the DOM and stuff

I'd like it if webpages would do that themself; but yeah then you could remove ads and stuff and they probably wouldn't like that
