100pcs 220 ohm Resistor 1W, 1 Watt ±1% Tolerance Metal Film Fixed Resistor, Multiple Values of Resistance Optional

Q: Wwhat is voltage rating of resistors?

Combining Ohms law with the power law you get the absolute maximum voltage a resistor can handle at V = √ ( P x R ). That is the square-root of the product of the power rating of the resistor in watts and the actual resistance of the resistor. The resistor will get very very hot approaching this value so allow a 50% safety factor and plenty of space to cool so as not to start a fire.

Q: Product title says 1W but the product picture shows 0.5W. Which is correct?

That is a question you should take up with the seller. To save work many sellers will take one picture of a product and use it with the description of a similar product. I've actually reported a seller who used a picture of a connector that had more pins and than was larger than the one being described. When I run across these I usually move on to a different seller. Who knows what a lazy seller may provide you, if they can't provide accurate pictures and documentation?

Q: What is the length of the leads?

The length of the two leads of the 1W resistor is 25±2.0mm each.
