Image on category page ecommerce

My site is pretty typical where you click on a category and it takes you to the page. There are a few sentences describing the category at the top followed by all the products. Products have their name and a small thumbnail type picture. Would it have any seo benefit to put a high quality image that represents the category on the page? Like above or below the items?

Received a different US visa category than I applied for

I am from germany and an employee of a large US-based IT company. I recently applied for a B1/B2 and I went through the whole process. I then went to the consulate last week and they accepted my application and told me that they would ship my passport to me as I ordered. I just received my passport via the mail but when I checked everything, I noticed that instead of B1/B2 the visa only states B1. Is this just a human error or is there more to it? And most importantly, is there anything I can/should do about this to change it to a B1/B2 and how long would this take?

Why is the triangulated category of motives easier than the abelian one?

There are several expository articles with the title “You could have invented [insert something mysterious here]” (a notable one being about spectral sequences, possibly it even started this genre). This question is somewhat similar in spirit to them.

Here it is stated that “Deligne first suggested that it might be easier to define the derived category $ DM(S,\mathbb{Q})$ of the hypothetical abelian category of mixed motives.” First time I heard about this, it seemed a little bit counterintuitive to me. We were doing some abelian stuff, why should passing to the derived category make anything any simpler? Of course, it is easy now to point to the success of Voevodsky and others and say that it was totally obvious.

The question is assuming you never heard about Voevodsky, Morel, etc., you are in the 1960’s, how could you arrive at the idea that the triangulated category is easier to construct than the abelian category of mixed motives?

What should be the Visa Category and required documents for my parents?

My home country is India. I will be traveling to the US for my Ph.D. with an F1 visa. I have already applied for the interview which is yet to take place. My parents wish to travel with me, both for visiting the US as tourists and helping me to get set up there. For such purpose what should my parent’s visa category be (B2??). Also, should they state that they will be going for tourist purpose or is it better is they say that they will be accompanying me? Also what documents are generally enough to demonstrate this purpose sufficiently?

WordPress Create/Set Category as Title Of Post

i am fairly new to php. I wanted a code snippet, to create post category from title of post. If the category same as title of post exists then set it. Else if the category doesn’t exist, create a category as the title of post and set it.

The code snippet should also update the category in case the title changes after post update.

I very well know that my need for this code would be need of others also. I also know that too many categories for post are bad. But it is for a better design.

Please help me out set a category/update the category as the exact title of post
