Publishing a multi-page newsletter with photos on a pc for the last 8 years. Have recently bought a Mac/book Air and a desktop to replace my old pc. Cannot duplicate or

Recently purchased a desktop and laptop MacBook Air after 23 years of using a PC. I publish a monthly multi-page newsletter (16 to 20 pages). Lots of pictures. Lots of text which I like to wrap around the photos. Have not been able to do that on the Mac using Pages. Couldn't help me at the Apple Store. Said I'd have to know where to end sentences to not interfere with photos. Really? In other words, unlike Publisher, you can't just input a photo and the text moves to allow it. Not at all acceptable. I have to keep my PC just to do the newsletters? Anything other program you can recommend?????
