Changing base64 code of an image?

[xxweekxx]

what is the quickest way to alter the base64 code of an image and still keep it the same.. i tried resizing but its not a big change... any ideas??

[woj]

what are you trying to do? what do you mean "base64 code"?

[Iron Fist]

Probably watermarking the content

Not sure what you are talking about but maybe this will help.....

Sounds like he's trying to get around a signature which disallows uploads of the same image?

He probably means MD5..

no i mean you know how you email someone and it converts it to base64, example i send a naked pic to your gmail, itll be sent in base64 format.. im noticing some blocking based on the base 64 code so id like to somehow modify the pic enuff so that the base64 code changes but the pic remains same.. ive tried resizing and it doesnt change much

Basically, you want to avoid spam / mailing filters.
There's not going to be a magic bullet solution for this.

I'd recommend reading the format specifications for JPEG and GIFs, work out where you can inject padding into the file/contents - and then just inject random data into there that won't be displayed when the image decodes.

I can't be the first to think of that, so I bet filters already check for it - but, that will achieve your purpose of changing the base64 output as much as you want.

Well no i rather just change the base64 code everyday, i dont need it realtime, just one change a day will solve my problem..


Still my question: is there a way to change without modifying the image.. maybe changing brightness, or some shit i dont know about..

bumpppppp

[just a punk]

You can't. You must to alter rte image to make it's MIME content (base64 or anything else) different.

[xxweekxx]

right.. what kind of alteration can i do but have the image still look the same?

[just a punk]

Open it in any image editor and just re-save it (in case of JPG), change it's EXIF etc. If it's a BMP/GIF/PNG file, draw a random pixel on it, or alter its palette data.

I just told you above. It's not 'real time'. It's a solution that will let you add as much random data into your images, and they'll look exactly the same.

[react]

The base64 encode of the image would definitely have changed significantly when you resized it. But perhaps they're looking at a specific part of the JPEG structure. You'd have to isolate that and change it.

Who are you spamming anyway?

[xxweekxx]

what do you mean change its exif??ahh i see it means like changing date, etc.. anyone know a free software for this?

[xxweekxx]

bump again.. need this asap.lol

[skinnay]

depending on the file type you can change a certain amount of meta data but i doubt this is what you need. what about converting it to a png or tiff?

Its a jpg image of someone, so i think jpg is best format.. i guess i can change some file info.... maybe brightness, etc..

There's been a lot of good advice in the thread that you're totally ignoring - at least 3 solutions.

Are you waiting for a packed lunch and written invitation?

Read his other threads and you'll get some idea of where he's going and what he's doing. Sounds like he's pretty new to it too.

well im looking for a definite solution.. as for what im doing you dont have slightest clue as of now i probably have 5+ different methods of making money

My point is that all your threads are looking for freebies

More power to you if you get answers, but if you're making so much $$$ why don't you just employ someone to consult on how to spam?

Ah right. I get irked by people who ask for advice, get 3 flavours of solid solutions, of which all are ignored, and the authors told they know shit

[xxweekxx]

this has nothing to do with spam at all.. sheesh.. basically i have an image i send to a group of users and i noticed its being picked up by a particular filter, so i tried resizing and its not helping... anyway all good.... what i wanted is simple and the solution provided here in this thread doesnt solve it.. im not stupid.. so im going to figure it out on my own...

and yeah GFY has helped me tons.. ive gotten solutions to 90% of my questions here... people here are actually smarter than scriptlance indian zombies...

PS the solutions didnt work..

1. I dont want a base64 encoder/decoder... #2 saving it as png/tiff is not an option, besides i tried just for the heck of it and no good... #3 good luck insert random crap to ur image when you are sending through webmail like gmail, basically impossible....

so you see how NONE of the solutions are viable...

anyway cheers all

Are you a fucking nonce or what?

Off the bat, you've dismissed all the options as 'unviable' - because
a) You can't explain yourself properly and
b) You don't have enough intelligence / patience / whatever to understand the solutions presented.

1) 'Inserting random crap' isn't going to be blocked. Listen closely: File formats, like images, movies, etc, have very specific structures, like header, information, data. Outside of these structures, you can place whatever fucking data you want - it won't affect the look of you image, it will change its base64 value, significantly.

There are multiple ways to do this, all of them simple:
1) Inject / change the exif data of the image.
2) Use a steganography program. Go on, google it.
3) Place data in the empty structure of the image.

None of these happen server side.

I don't even know why I'm wasting my time on this. It seems that if you've tried different formats and the same thing is happening, you're probably getting filtered by what's in your image optically. Stop spamming viagra.
