[Request] Replace a single specific image on a site.
You really need to learn JavaScript.
You won't be able to create GreaseMonkey scripts without it.
Check this link to see why the code you've written cannot work:
http://www.w3schools.com/jsref/jsref_replace.asp
- src is null (you need to put the page source code into the src variable
- .replace function returns the result, but you are not saving it anywhere
- etc...
PS: @namespace should be a unique url to determine who made the script.
for ex.: you can use your GreaseFork profile URL.
OK, i understand why my script doesn't make sense, i'd have to define the variable "src" firs and probably do a loop to check al images or something.
The problem is i'm not a coder/programmer, i don't need this for work or school or anything, its just something i would like to use for myself and i just don't see myself learning javasript just for that. I thought it was much simpler, just a matter of few lines of code but it seems like it's more complicated than that.

For me it works like a charm. just posting it if anyone else needed it.

Gubangu, how do you use it? Edit: nevermind :smile:
if i want to replace, just for example, greasyfork's logo on the home page with a shared uploaded pic, editing the lookup table like this does work:
let lookup_table = {
'https://greasyforks.org/assets/blacklogo96-941a633c971b25c0c9e982ed499b5d8c.png':'http://fap.to/images/thumb/53/741/74199004.jpg',
};
I don't know why a dozen tries didn't work but this does. voilà! I too have wanted a script like this, to replace a little grey arrow, say, with a bigger green arrow. I'll see if this does the trick. Thanx for your request!
[Request] Replace a single specific image on a site.
First of all i would like to explain that i have almost zero knowledge about web design and scripting. I have no real idea how Greasemonkey works and maybe i'm way off on this.
To no avail I've been looking for a FF and/or Chrome plugin, that would replace a single specific image on a website with a custom one. For example when i open www.my-page.com/* which somewhere contains an image, lets say www.my-page.com/public/style_images/logo1.gif would like for the browser to display an image i uploaded to a hosting somewhere www.some-image-host.com/images/923467304/fakelogo.gif. The image would be of the same size (resolution) so it shouldnt breake the page in anyway.
While googling for such a plugin i came across Greasemonkey which i suppose should have no problem doing this, but i dont know how.
I installed Greasemonkey and "made" a script but it doesn't do what i think it should:
// ==UserScript==
// @name Name of my script
// @namespace don't know what to put there
// @description My script description
// @include *www.my-page.com*
// @version 1
// @grant none
// ==/UserScript==
src.replace('www.my-page.com/public/style_images/logo1.gif', 'www.some-image-host.com/images/923467304/fakelogo.gif');
What am i doing wrong or what am i missing?
Thank you in advance for your help.
