My drupal creates thumbnails of my uploaded image (thumbnail, medium and large). How can I stop drupal from creating these?
I don't want to have redimensioned images, I want original size.
PS: Drupal creates 3 images per uploaded image, so, for me are lots of nodes.
Thank you very much in advance!

The image styles isn't generated until the first time you use them. So, if you only use the original image in your theme and also inside your administration the thumbnail, medium and large images will never be created.
To use the original image in the backend you will have to go to structure/types/manage/<contentent_type>/display and change the image style that is used for displaying your field.

How can I compress image using Laravel or Image intervention to optimize Images?
Your suggestions are important
You can try to use
public Intervention\Image\Image encode([mixed $format, [int $quality]])
->... // any other methods from image intervention
->encode('jpg', 75);
The quality parameter is optional but is required in case of jpg.So you can check the format if it is jpg or not.
You can read more about it from encode docs

I have a set of images on a data set and I want to create an application(on android initially) so that the application would be able to take an image and match it with an image on my data set. I tried using image recognition algorithms but I had very poor recognition chances. Is there any way to unobtrusively embed data on the image itself such that when a printed version of the image is scanned by the application, it would be able to extract the embedded data? I need some direction in this regard because I seem to be punching in the dark since I haven't worked on anything like this before.
Thanks

I'm developing a game, but I don't know how to proceed. I'm showing an image and after 5 sec it disappears and then 4 images pop up. 3 different images and 1 image that was the image that disappeared.
I don't want to show the same images everytime, so I want random images to be shown everytime you start the application. But how can I make sure that the image that disappears, also is shown in the other 4 images?
And is it possible to change the places of the 4 images everytime?
I hope someone will/can help me!
Thanks!!
You can do something like :
name your images like image0.png, .. image4.png etc..
create a random no using ->
NSInteger randomNumber = arc4random() % 5;
Which will generate no.s form 0 to 4.
3.now use something like image%# where %# would be the randomly generated number.
Mind you this is pretty basic solution. there could be better solutions out there.

We have seen a user avatar will have different sizes on Facebook, Twitter, etc.
For example, Twitter has 3 different avatar sizes: 24x24, 48x48, 128x128; Facebook mainly has 50x50 and 180x180>.
I am wondering if there is a standard thumbnail size that a website should adopt, or it's all solely based on the design?
Thanks.
Like you say its just down to the design of your site. If in doubt, adopt the same resolution as a big player like Twitter, and allow users to upload a larger image which will give you the flexibility to show a larger version if someone clicks through to their profile.
I found this page to be most useful.
https://en.gravatar.com/site/implement/images/
I plan to allow users to upload their own larger image and using similar rules as above, any dimension within range requested will auto generate the size for that image. So no matter if I want 50px or 51px, my site will generate the first request.
Obviously that requires software custom or other and is out of scope of your tags.

I have many types of diagrams in my paper.
I use at the moment horizontal pages to make pictures readable.
I would like to know how you can remove LaTeX margins from pages where there are pictures.
How can you have no margins for pictures in LaTeX?
Either diddle the various variables directly or use the geometry package.
LaTeX uses a lot of variable to describe the page, so setting them directly is a hassle, I really reccomend using geometry.
And remember there is a silent 1 inch margin. Moreover how close to the edge of the page you can actually print is dependent on you printer. Most won't actually let you get to the edge on any side.
The changepage package can be used to locally change the size of the area that content is put in. Documentation within the .sty file until I get around to writing a real manual.
I did this exact thing before. Here's the code:
\newenvironment{changemargin}{%
\begin{list}{}{%
\setlength{\textwidth}{\paperwidth}
\setlength{\textheight}{\paperheight}
%\setlength{\oddsidemargin}{-1in}
%\setlength{\evensidemargin}{-1in}
\setlength{\topmargin}{-1in}
\setlength{\topsep}{-1in}%
\setlength{\leftmargin}{-1.5in}%
\setlength{\rightmargin}{-1.5in}%
\setlength{\listparindent}{\parindent}%
\setlength{\itemindent}{\parindent}%
\setlength{\parsep}{\parskip}%
}%
\centering%
\item[]%
}{\end{list}}
On the page in question, I also used \clearpage, \pagestyle{empty} and enlargethispage{...}.
You can specify the width of the figure to be bigger than \textwidth.
I think includegraphics is the non-clipping version, (as opposed to includegraphics*)
I assume this would work as long as the vertical size would fit on the page.
Otherwise I'd look on CTAN for packages which allow you to change the margins on the fly.
