How can I write a strapi query to get my posts and image from a category content type - strapi

Question

I created a collection type 'posts' and created many posts. Now I made another collection-type of category with ['softwaresApps','gifts','technology'] title that holds relations of posts. then i tried fetching with http://localhost:1337/api/categories?populate=*" and get:
{
"data": [
{
"id": 1,
"attributes": {
"title": "Technology",
"createdAt": "2022-01-09T00:43:05.899Z",
"updatedAt": "2022-01-09T00:45:26.131Z",
"publishedAt": "2022-01-09T00:44:04.298Z"
}
},
{
"id": 2,
"attributes": {
"title": "Gifts",
"createdAt": "2022-01-09T00:43:48.196Z",
"updatedAt": "2022-01-09T00:43:53.979Z",
"publishedAt": "2022-01-09T00:43:53.961Z"
}
},
{
"id": 3,
"attributes": {
"title": "softwares&apps",
"createdAt": "2022-01-09T00:48:23.706Z",
"updatedAt": "2022-01-11T00:06:48.130Z",
"publishedAt": "2022-01-09T00:49:59.571Z"
}
},
{
"id": 4,
"attributes": {
"title": "HomeSlider",
"createdAt": "2022-01-15T15:06:23.122Z",
"updatedAt": "2022-01-15T15:06:30.272Z",
"publishedAt": "2022-01-15T15:06:30.259Z"
}
}
],
"meta": {
"pagination": {
"page": 1,
"pageSize": 25,
"pageCount": 1,
"total": 4
}
}
}
I can't seem to find my posts relations in the data. I need a query that can help me fetch all the posts & images from the cateories.

I have figured it out. thanks to #IceJonas, his link:

It turns out populating with http://localhost:1337/api/categories?populate=*" is not going to cut it. I found the solution whereby you have to populate deeper using - http://localhost:1337/api/categories?populate[posts][populate]=* and you will populate all the relations including their images.

"article": "A digital photo frame lets you easily add images—including beautiful travel shots and family photos—to the frame from anywhere. Whether you’re giving a frame as a gift and plan to upload photos remotely, or you just want a great frame for yourself, the Aura Mason is the best frame we’ve used. Its 8.57-inch display is sharp, bright, and vivid, and in our tests it was the simplest to set up. On top of that, it has a good-looking design.\n\nOf all the frames we tried, the Aura Mason came the closest to mimicking a regular photo frame. The Mason is straightforward to set up and use, and remotely loading photos is a breeze (the free Aura app works with Android and iOS phones). With this frame it is easy to add photos on the app or through a web uploader. From the intuitive design of the app to the frame’s pared-down interface, the Mason is not just for the tech-savvy.\n\n\n### The Aura Mason\nThe Aura Mason Luxe is an upgrade to the Mason, with a larger price tag. That extra cost adds a slightly larger 2K screen and video capabilities onto everything we already like about the Mason frame. But even though the video capabilities are nice, we don’t think they’re truly necessary in order to enjoy a digital picture frame.\n\n\n\nThe [Aeezo Portrait](wirecutter.com) 01 is considerably cheaper than our other picks (it’s nearly half the price of the Aura Mason), and it’s surprisingly good.
