If you are in it to win it (being successful in business) then you don't take shortcuts and you don't look for 'free floral pics' for your website.
You make your own floral arrangements, you take pictures of your products and you put those images on your website.
Anything else is false advertising.
Have you taken any business/marketing classes?
It might be a good move for you to do so!
Additional:
You deal in flowers - take your own pictures of them!
And if you are selling flower arrangements - you put pictures of your arrangements on your website.
In a prior post in Sept you said you were about to graduate as a Floral Designer.
Did you talk to your career development center at your school?
There is something very basic that you are not understanding and I'm having a hard time reconciling a Floral Designer not being able to take some pictures of a few flowers for her own business website.
In the time it took for you to post this - and alter your question - you'd have your pictures published to your web site by now.
Spending money on Adobe Photo Images is not making any sense.
