Hi guys not sure if this is the right place to post this but just wondering what is the rules regarding posting images of individual attempts for a question you have asked, i.e. if I have a question, can I show my attempt at the question or understanding of it by uploading a image that is clear?
Most important thing is to use MathJax whenever possible. People will invest their time in order to answer your question, so please invest your time in order to ask it properly: Typesetting formulae in MathJax is one aspect of this.
Images should be used to depict an "actual image" like for example the physical setup of an experiment. They should not be used for formulae.
Also note that it is a good idea to only use the Math SE internal uploading feature as opposed to linking external sources. I don't think there is a rule prohibiting external links, but as those links will be broken when an external image gets deleted, the use of external hosts somehow goes against the SE spirit:
Questions should be of value to future visitors and if your question can no longer be understood because an external image source is now missing, that value has been lost.
The better place for questions like this is Math.Meta. However, I'll answer it here.
You can upload pictures to your question, and that is perfectly acceptable, but I would always recommend writing out any workings you've done using Mathjax - sometimes handwriting (like mine) can be hard to read and the use of Mathjax eliminates that issue. For diagrams or drawings, using images is a good idea however. You can upload them by clicking the icon shown in the picture below, when you go to ask your question.
As hardmath kindly pointed out, you can only upload images if you have $10$ reputation points. Link here showing that.
