Design – Options to create an image library for products

I am not even sure how to ask this question.


I am building a platform for them to use product companies that will take online orders from their customers. It's a fairly simple concept, but the hard part will be importing your inventory. Let's say the business sells wine. Well, importing your wine list is one thing, but how should I manage to choose which wine image to display for each product?

It seems absurd to force them to choose an image for each product. Not only do I think the business owner shouldn't have to choose an image, but I don't trust him to choose a "good" image. If I let you choose an image, that will open the floodgates so that images of terrible quality are all over my SAAS.

SAAS is run within a specific industry, that is, wine sellers. Then, in a perfect world, the business owner will load their products through a spreadsheet of some kind, and the system will be smart enough to associate product images with products.


What are some options to build an image library for something like the wine industry? The obvious answer is that we begin to manually choose the images of the most common wine products and then increase the list as companies insert products without images. I am a developer, so doing anything manually grinds my gears. Any ideas on some other strategies?

Write a macro to create a new tab and name that tab based on a cell value in Google Sheets

I would like to have a Macro that generates a new tab and name that tab based on a cell value.

There is a tab called 'Dashboard'! in which the user enters information in the assigned cells. Next, I would like there to be a button on which the user clicks, on which the information on the 'Dashboard'! it is copied to a new leaf. That new sheet must receive the name that the user has entered in the cell B2 (the name of the day) and cell phone C2 (the date of that day), followed by the word "Training".

I have successfully recorded a Macro that does most of this, but naming the new tab based on a cell value seems impossible. I have manually changed the name of the tab, which is perfectly displayed in the Macro. However, I don't know how to make this name. & # 39; dynamic & # 39;.

Thanks in advance for any help, sorry in advance if this question is redundant and / or is improperly worded.

OCTAVE / MATLAB Create script with vectors and use a colon

I need to do a script in Octave where I am given vec1 and num and I need to produce vec2.
Vec1 is a vector of floating point numbers and num is a single floating point number.
I need to produce a vector identical to vec1 but all odd elements are replaced with the num value and store this result in vec2.

For example:
vec1 = (1 2 3 4 5 6 7 8 9 10); num = -1;

This should produce
vec2 = -1 2 -1 4 -1 6 -1 8 -1 10

What I did was:
size = length (vec1);
vec1 (vec (1): 2: vec1 (size)) = num;
vec2 = vec1

But in the grades, he says I have an octave error but I'm not sure why.
